It came up in this webcomic I'm reading, and it made me wonder…
Do you have sexy pictures (or videos) of (at least one of) your partner(s) on your phone?
It's up to you to define "sexy". The comic implies at least partial nudity; I'd say, as a guideline, it should be more intimate than a normal portrait shot, arousing in nature. Something most ppl wouldn't want to show their boss or parents.
If you don't have a "partner" or don't use that term, then an ex or someone close to you.
